I've found a fix to the jerkyness problem. While in 1st rev the engine to 4K + with the clutch in. Keep your foot on the throttle and dump the clutch while depressing the throttle. The rev limiter will kick in at 7500 RPM. That will be your signal to engage the clutch again and shift into second. Dump the clutch again while maintaining the throttle and you'll be off without any jerking..... If this is to agressive for you the alternative is to get the automatic. Problem solved!

You do know how much a clutch costs right? Why would you tell people to dump a clutch all the time when driving normally? Unless my understanding of clutch dumping is wrong, that will tear it up a lot faster. A might have been nice at the end of this to stop people who don't know from following your "advice"

I'll agree with everyone saying to ease out at 1500rpm into first and go slow into second. It just takes some getting used to, although I still get caught sometimes and jerk around a bit. Sometimes I just wind out 1st gear up to 5k to make shifting to 2nd easier. Plus it sounds awesome :P

Seriously if you don't realize that reving your car to red line and dumping the clutch isn't tounge in cheek as a solution for a jerky start then you shouldn't be driving a car! No smilie need on that one.... Can you imagine someone taking that advice seriously? Come on..... Every light doing a massive burn out?

No offense to any of the posters but its pretty basic driving here to get the car to pull away without jerking. Its not the car - its the driver not adjusting to a new vehicle. Once you spend a little time with the car you'll figure out how to use the clutch and shift properly.

It took me awhile to adjust from the 350Z, and I had lots of issues because of clutch pedal "play" (funky engagement point) and clunky shifter.

I don't see it so much as that for me. Even after I've fully engaged the clutch, and I'm in first gear accelerating, say from 2500rpm up, if I do it slowly and smoothly, the car jerks/bucks slightly once or twice (not really a large buck, but it hesitates and the RPM fluctuates slightly). It's weird. It almost seems as if the electronic throttle is modulating up and down a few times.

If its uncontrolable then it needs to go in for repairs.

Understood. Magazines gripe Z/G having an on/off abrupt feeling with the clutch engagement.

When you release the clutch in 2nd gear too slow or fast will be abrupt. This is where you need to pivot your foot (ankle) back as you let out the clutch so it doesn't engage too abruptly. It's hard to describe. Let's say the ball of your foot is on the floor when you start in 1st. When you go to 2nd, lift the ball of your foot a few inches off the floor and quickly and fully press down the clutch pedal with your toes, then engage 2nd, and pivot your foot back as you release the clutch pedal before applying gas.

Pressing down the clutch pedal quick before easing it out seems to smooth out the engagements regardless of RPM... and I can get things smooth and fast as low as under 2k RPM.
